On Some Turtle Remains from the Ft. Pierre. 
Contributions from the Paleontological Laboratory, No. 37. 
BY GEORGE WAGNER. 
Among the material collected this summer (1898) by the Univer- 
sity Geological Expedition are some remains of turtles, from the 
Ft. Pierre. Though fragmentary, they are worthy of study; firstly, 
because they seem to be the first material of this nature collected 
from this horizon in Kansas, and almost the first from any locality; 
and secondly, because of their remarkable relation to the turtles 
described from the underlying Niobrara. 
Toxochelys latiremis Cope. 
A specimen consisting chiefly of the back part of the skull and a 
part of the upper jaw must evidently be referred to this species. 
The material (Kas. Univ. Museum, No. 1221) is in the poor state 
of preservation so common with Ft. Pierre fossils; it shows, how- 
ever, fairly well most of the quadrate, the basisphenoid, and parts 
of the pterygoid, maxillary, basi and supra-occipital, and _par- 
ietal. The sutures are indistinct except between the quadrate and 
pterygoid. (See fig. 1.) 
On comparison of these elements with the corresponding parts 
of two skull of Z /atiremis collected from the Niobrara, (Kans. 
Univ. Mus. Nos. 1214 and 1215),* I fail to find any difference in 
specific characters; even in size they are nearly identical. A dif- 
ference in the appearance of the articular surface of the quadrate 
is undoubtedly due to difference in compression. This specimen 
was discovered by Professor Williston at Eagle Tail Creek, near 
Sharon Springs, Kas. 
Another specimen (Kansas University Museum 1222) con 
sists of fragments of a lower jaw, including one nearly complete
